preparing us for that genus. The discal cell is retreating, nervules 

 longer than in Sesia. Like Sesia, this parallel genus affords two 

 Groups. The first contains H. gracilis, nob. which approaches the 

 opposed Group of Sesia, in appearance. In this species the discal cell 

 is free and uncrossed by any longitudinal fold or scales. The head 

 approaches Sesia in structure, while the characters in their entirety 

 induce us to refer it as a Group of the present genus, with which its 

 squammation agrees. The second Group contains S. thijshe Fab., S. 

 fuscicaudis Walk, and probably *S'. rujicaudls Kirby, non Walker, and 

 is the more typical Group of the genus and upon which the above 

 diagnosis is generally based. The palpi exceed the clypeus greatly 

 and are converging at the tips. The discal vein is longitudinally 

 crossed by a line of scales, though a thickening of the discal mem- 

 brane beneath is not appreciable. 



Haemorrhagia gracilis, nov. sp. (PI. 3, figs. 1 & 2'^.) '' 



Form somewhat small and slight. Head and thorax above, clothed 

 with olive green appressed hair; basal segments similarly colored. 

 Palpi, black at the tips, whitish beneath. Orbits of the eyes white, in 

 front of these, a few whitish scales. Laterally the under thoracic parts 

 are clothed with long white hair, extending from behind the eyes to 

 base of secondaries. Wings, vitreous ; anterior pair largely dark red 

 at base, the scales encroaching on the discal cell from the base. Discal 

 cell free. External margin with a moderately broad, dark red, even, 

 band, which is brighter stained apically, narrowing to internal angle. 

 Internal margin clothed with dark red scales. Posterior wings dark 

 red, paler on internal margin and above anal angle. Centrally, these 

 are vitreous, the diaphanous space crossed hj Jive nervules. Abdomen, 

 except basal segments, dark red ; third basal segment fringed anteri- 

 orly with pale hairs; fourth, dorsally with a few similar colored ap- 

 pressed hairs; fifth and sixth with a few pale lateral hairs. Anal tuft 

 black laterally, centrally pale red. I nder surface pale red ; abdomen 

 pale red, with a central subobsolete series of pale spots composed of a 

 few agglomerated hairs. Laterally, spots of similarly colored hair at 

 the base of the segments; posteriorly the segments show a narrow edg- 

 ing of black hairs. The sides of the abdomen show sub-tufts fringed 

 above with pale yellowish, similarly colored hair, to that forming the 

 lateral and central series of abdominal spots Anal tutt concolorous 

 with abdomen beneath ; extremities of anal hairs, black. xVnterior 

 femora clothed with thick white hair; similar hair also covers the un- 

 der thoracic part centrally. Anterior tibite pale red, as are also the
